CEC_TX_READY_ST , IO, Address 0x93[0] (Read Only)
Latched status of CEC_TX_READY_RAW signal. This bit is only valid if enabled via the corresponding INT1 or INT2 interrupt mask bit.
When the CEC TX successfully sends the current message this bit is set. Once set, this bit will remain high until the interrupt is cleared
via CEC_TX_READY_CLR.
Function
CEC_TX_READY_ST
0 (default)
1
CEC_TX_ARBITRATION_LOST_ST , IO, Address 0x93[1] (Read Only)
Latched status of CEC_TX_ARBITRATION_LOST_RAW signal. This bit is only valid if enabled via the corresponding INT1 or INT2
interrupt mask bit. If the CEC TX loses arbitration while trying to send a message this bit is set. Once set, this bit will remain high until
the interrupt is cleared via CEC_TX_ARBITRATION_LOST_CLR.
Function
CEC_TX_ARBITRATION_LOST_ST
0 (default)
1
CEC_TX_RETRY_TIMEOUT_ST , IO, Address 0x93[2] (Read Only)
Latched status of CEC_TX_RETRY_TIMEOUT_RAW signal. This bit is only valid if enabled via the corresponding INT1 or INT2
interrupt mask bit. If the CEC TX fails to send the current message within the number of retry attempts specified by CEC_TX_RETRY
this bit is set. Once set, this bit remains high until the interrupt is cleared via CEC_TX_RETRY_TIMEOUT_CLR.
Function
CEC_TX_RETRY_TIMEOUT_ST
0 (default)
1
CEC_TX_RETRY[2:0] , Addr 80 (CEC), Address 0x12[6:4]
The number of times the CEC TX should try to retransmit the message if an error condition is encountered. Per the CEC specificationthis
value should not be set to a value greater than 5.
Function
CEC_TX_RETRY[2:0]
001 (default)
xxx
CEC_TX_NACK_COUNTER[3:0] , Addr 80 (CEC), Address 0x14[3:0] (Read Only)
The number of times that the NACK error condition was encountered while trying to send the current message. This register is reset to
0b0000 when CEC_TX_ENABLE is set to 1.
Function
CEC_TX_NACK_COUNTER[3:0]
0000 (default)
XXXX
CEC_TX_LOWDRIVE_COUNTER[3:0] , Addr 80 (CEC), Address 0x14[7:4] (Read Only)
The number of times that the LOWDRIVE error condition was encountered while trying to send the current message. This register is
reset to 0b0000 when CEC_TX_ENABLE is set to 1.
Function
CEC_TX_LOWDRIVE_COUNTER[3:0]
0000 (default)
XXXX
Description
No change
Message transmitted successfully
Description
No change
The CEC TX has lost arbitration to another TX
Description
No change
CEC TX has tried but failed to resend the current message for the number of times specified
by CEC_TX_RETRY
Description
Try to retransmit the message 1 time if an error occurs
Try to retransmit the message xxx times if an error occurs
Description
No error condition
The number of times the NACK error condition was encountered
Description
No error condition
The number of times the LOWDRIVE error condition was encountered
